My niece and her husband moved into a house with a couple very tall castor bean plants about a year ago. Knowing that they were extremely poisonous and having a toddler, she cut them down and tried to dig out the roots. Unfortunately new plants keep popping up either from the seeds previously dropped or from the roots not taken out. She pulls them out is soon as she sees them but more keep popping up.

Is there anything she can do to completely eradicate this plant from her yard?

She is very concerned for the safety of her little one and soon to be second little one.

Any help would be greatly appreciated!!!!

Castor Bean Plants don't grow back from the roots so your niece is dealing with seeds. Tell her to keep pulling. But, she should be wearing gloves she doesn't use for anything else. Disposable gloves would work well.

I doubt something like Preen would work as the bigger the seed, the less effective it is but its worth a try.

Trust me! The seeds will keep coming up for years, so pull them as soon as you see them. I thought I had gotten rid of them 20 some years ago, but last year when they leveled the ground for a new shed...surprise!!!
